Introduction:
This junction box is made of high-quality ABS material designed to be assembled with various electrical componets according to different control function requirement.It can be widely used in Indoor and outdoor electrical , communicate and fire equipment, ironmaking & steelmaking , Stone oil chemical, electronic plants.
Types of waterproof abs plastic junction box on the current market: The first type: traditional. Structure features: the shell with the back opening, the shell is provided with an electrical terminal (slide block), the solar cell template power output end of each junction belt and the corresponding electrical terminal input end (distribution hole) electrical connection, the cable through the hole on one side of the shell extended into the shell and electrical terminal on the other side of the output end hole electrical connection. Advantages: clamping connection, quick operation, easy maintenance. Disadvantages: due to the existence of electrical terminals, the volume of the junction box is large and the heat dissipation is poor. The cable hole in the housing will cause the waterproof performance of the product to decrease. Wire contact connection, small conductive area, connection is not reliable.
waterproof abs plastic junction box second type: sealing sealant sealing compact. Advantages: due to the use of thin sheet metal terminal solder, small size, and has better heat dissipation, stability. Because of sealant sealing, it has better waterproof and dustproof performance. Provide more flexible connection scheme, according to different needs can be used sealing glue and non-sealing glue two ways. Disadvantages: once there are problems after sealing, maintenance is not convenient. The third type: glass curtain wall special type. Advantages: Because it is used for low-power PHOTOVOLTAIC panels, the box system is more compact and exquisite, and will not affect the indoor lighting and beauty. Is also the design of sealant sealing, with good thermal conductivity, stability and waterproof and dustproof performance. Disadvantages: Because of the tin welding connection, the cable lead extends into the box body through the outlet holes on both sides, it is very inconvenient to weld to the metal terminal in the long and narrow box body. Ly0803-1 junction box adopts the form of insert in structure to avoid the above inconvenience of processing.
